Extender based on skimmed milk to transport cooled semen or preservation at 5° C or 15° C, as well as for centrifugation pre-freezing. Use dilutions of 30 to 50 million/ml for cooled transport, respecting the minimum of 2 parts of extender to 1 part of semen.
In case of samples requiring centrifugatoin before cooled transport, resuspend the sperm also between 30 to 50 million/ml. Suitable for most stallions, best cost/benefit ratio.
